Chasing rainbows...  If you like the challenge of 20 inch trout on #20 dries, the Missouri River is the river for you. PRO headquarters is minutes from this tailwater, one of the finest trout streams in the country.

With flows regulated by upstream dams, the fishery is very much like a giant spring creek and is unusually productive in terms of numbers and size, and the action is year-round.

Spring and early summer provide numerous mayfly and caddis hatches to drive the river's large rainbows and brown trout into feeding frenzies. Warm weather brings morning trico hatches, hanging over the water like clouds. Big trout cruise in their midst, slurping mouthfuls of the tiny morsels. Grasshoppers also appear with the warmer days. The violent strikes to a hopper imitation are in stark contrast to the subtle rises for tricos and other smaller aquatics.

Fall means frequent afternoon mayfly hatches dominated by the blue wing olive, spectacular streamer and nymph fishing, and crisp, clear autumn weather. Often the spectacular scenery of the Missouri below Holter is overlooked due to the high quality of the fishery. But when you take time to appreciate the surrounding landscape, you'll often want to drop your rod and grab the camera.

Founded in the 1860s, Helena is about midway between Yellowstone and Glacier National Parks. At one time harboring the highest density of millionaires in the world, Helena's historic mansions, St. Helena Cathedral, museums, and other attractions make it a sensational base for your vacation.
